Appl. No.:

16/422755

Inventors:

- Mountain View CA, US
John Colgrove - Los Altos CA, US
Robert Lee - San Carlos CA, US
Joshua Robinson - Brenham TX, US
Igor Ostrovsky - Sunnyvale CA, US

International Classification:

G06F 11/10

Abstract:

A method for proactively rebuilding user data in a plurality of storage nodes of a storage cluster is provided. The method includes distributing user data and metadata throughout the plurality of storage nodes such that the plurality of storage nodes can read the user data, using erasure coding, despite loss of two of the storage nodes. The method includes determining that one of the storage nodes is unreachable and determining to rebuild the user data for the one of the storage nodes that is unreachable. The method includes reading the user data across a remainder of the plurality of storage nodes, using the erasure coding and writing the user data across the remainder of the plurality of storage nodes, using the erasure coding. A plurality of storage nodes within a single chassis that can proactively rebuild the user data stored within the storage nodes is also provided.

Abstract:

A method of operating a remote procedure call cache in a storage cluster is provided. The method includes receiving a remote procedure call at a first storage node having solid-state memory and writing information, relating to the remote procedure call, to a remote procedure call cache of the first storage node. The method includes mirroring the remote procedure call cache of the first storage node in a mirrored remote procedure call cache of a second storage node. A plurality of storage nodes and a storage cluster are also provided.

H04L 29/06
H04L 12/58

Abstract:

An e-mail system is running with a first synchronization mechanism synchronizing first application data between a service and a client computing system. A second synchronization mechanism synchronizes second application data between the service and the client computing system, using a second protocol. When a given proportion of the application data has been synchronized by the second synchronization mechanism, the application is controlled to use the second application data synchronized according to the second protocol.

International Classification:

G06F 3/06
G06F 11/00
G06F 11/20

Abstract:

A plurality of storage nodes cooperating as a storage cluster is provided. Each of the plurality of storage nodes has storage memory. Each storage node of the plurality of storage nodes is configurable to direct erasure coded striping of data of one of an Mode or data segment across the plurality of storage nodes of the storage cluster, with at least one storage node of the plurality of storage nodes having a differing amount of storage capacity of the storage memory from an amount of storage capacity of another storage node in the plurality of storage nodes. A method of storing data in a storage cluster is also provided.

G06F 3/06

Abstract:

A storage cluster is provided. The storage cluster includes a plurality of storage nodes within a single chassis. Each of the plurality of storage nodes has nonvolatile solid-state memory for storage of user data. The plurality of storage nodes are configured to distribute the user data and metadata throughout the plurality of storage nodes with erasure coding of the user data such that the plurality of storage nodes can access the user data, via the erasure coding, with a failure of two of the plurality of storage nodes. The plurality of storage nodes are configured to employ the erasure coding to reconfigure redundancy of the user data responsive to one of adding or removing a storage node
